7 Warning Signs of a Mouse Infestation
Mice are secretive and mostly active at night. A single mouse can become dozens within weeks. Look for these warning signs in your London home or business.
Mouse Droppings
Small, dark, rice-shaped droppings (3–6mm) along skirting boards, in kitchen cupboards, behind appliances or near food storage areas.
Gnaw Marks
Mice gnaw constantly — look for bite marks on food packaging, cables, wood, plastic and soft furnishings. Fresh gnaw marks are lighter in colour.
Scratching at Night
Light, rapid scratching or scurrying sounds in walls, ceilings or under floorboards — particularly between 11pm and 4am when mice are most active.
Nesting Materials
Shredded paper, fabric, insulation or cardboard gathered into a ball shape — usually hidden in quiet areas like loft insulation, behind appliances or in cavity walls.
Grease Marks
Dark smear marks along walls, skirting boards and floorboards caused by the oils in mice fur as they travel the same routes repeatedly each night.
Musky Ammonia Smell
A distinctive musky, ammonia-like odour — particularly strong in enclosed spaces like cupboards, loft areas or behind kitchen units — is a clear sign of mice.
Damaged Food Packaging
Gnawed holes in food boxes, bags or containers in your kitchen or pantry. Mice contaminate far more food than they eat — a serious health risk.

Why Mice Are a Serious Problem in London
The house mouse (Mus musculus) is one of the most common pests in London homes and businesses. London's dense housing, restaurant waste and Victorian-era buildings with countless gaps and cavities create ideal conditions for mice to thrive and breed rapidly. A single female mouse can produce 5–10 litters of 6–8 pups per year — meaning what starts as one or two mice quickly becomes an infestation of dozens.
Mice are not just a nuisance. They carry serious diseases including Salmonella and Listeria, contaminating kitchen surfaces and food. They gnaw through electrical wiring (a leading cause of house fires), damage insulation, chew through pipes and destroy stored documents, clothing and food stocks.
Our Mice Control Treatment in London
Our certified technicians carry out a comprehensive inspection of your property to identify all mouse activity, nesting sites and — crucially — every entry point. We then implement a targeted treatment programme combining professional snap traps, multi-catch traps and tamper-proof rodenticide bait stations.
The final and most important step is proofing: sealing every gap, crack and hole that mice are using to enter your property. Mice can squeeze through a hole no bigger than a pencil (6mm) — we use stainless steel wool, wire mesh and appropriate sealants to close every access point we find. This is what separates a permanent solution from a temporary one.
